In 2025, the open-source graphics landscape, particularly the Mesa project, witnessed remarkable advancements with significant contributions and improvements. Leading the charge were developers from Valve and AMD, who made the most code contributions to the Mesa project. A key contributor from Valve focused on the RADV Vulkan driver, with substantial input from AMD’s Marek Olšák on RadeonSI and Gallium3D enhancements, continuing their role as major proponents of open-source graphics innovation.
Throughout the year, Mesa released several major updates (versions 25.0-25.3) that brought in new capabilities such as Vulkan 1.4 support and AMD RDNA4 readiness. Performance updates were a highlight, with Valve integrating DLSS support for the NVK driver and AMD enhancing Anti-Lag and FSR 4 features for the RADV driver. Other notable advancements included AV1 encode support, improved ray-tracing performance, and Intel’s memory pool optimizations, collectively delivering significant speed boosts.
Additionally, the Mesa project took steps to modernize its ecosystem by deprecating older components like Clover OpenCL and VDPAU, making way for newer alternatives such as Rusticl and VA-API. New functionalities introduced include mesh shader support and cross-platform system call interfaces.
In a significant strategic shift, AMD ceased development of its AMDVLK driver in May 2025 to focus solely on the open-source RADV Vulkan driver within the Mesa ecosystem. Comparative benchmarks between the final AMDVLK release and the RADV driver showcased RADV’s enhanced ray-tracing performance on Radeon RX 9070 and RX 9070 XT graphics cards, delivered through the new Mesa 26.0-devel on Ubuntu 25.10 with Linux 6.18 kernel.
On the NVIDIA front, the open-source Linux driver ecosystem also saw substantial progress. The Rust-based Nova driver was actively developed and submitted for Linux 6.15, with NVIDIA engineers in co-maintainership. It targeted RTX 20 series and newer GPUs, showcasing remarkable strides. The Mesa NVK Vulkan driver benefitted from NDA documentation support from NVIDIA, resulting in notable performance improvements. Furthermore, with the addition of Blackwell support in Linux 6.16 for Nouveau, the competitive edge between open-source (NVK/Nouveau) and proprietary drivers was evident. Benchmarks demonstrated performance nearing that of proprietary drivers on RTX 40 and 50 series GPUs, with Vulkan machine learning approaches closely rivaling CUDA’s efficiency.
Overall, 2025 marked a year of exceptional progress for the open-source graphics drivers, driven by the tireless efforts of the contributors and organizations dedicated to advancing the capabilities and adoption of open-source solutions across various hardware platforms.
